Hi friend, Here is the required answer:-
The human respiratory system begins from the nose . In human being air is taken through the nostrils. The air passing through the nostrils is filtered by fine hairs which line the passage.The passage is also lined with mucus which helps in this process.
From here, the air passes through the throat and into the lungs.Rings of cartilage are present in the throat,. They ensure that the air passage does not collapse. Within the lungs, the passage divides into smaller and smaller tubes which finally terminate in balloon-like structures called alveoli.
The alveoli provides a surface where the exchange of gases takes place . The walls of the alveoli contain an extensive network of blood vessels. When we breathe in, we lift our ribs and flatten our diaphragm and as a result our chest cavity becomes larger,. The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveolar air is taken up by the blood in the alveolar blood vessels to be transported to all the body cells.
Hope this helps you....
